Document Summary
Ion: atom or molecule that had gained or lost electrons, giving it an electrical charge. Acid: acids have a low ph, mild acids are sour, strong acid will dissolve in just about anything. What are the different types of energy: potential- energy of position, condition, or composition. Chemical energy- pe stored in chemical bonds. Nuclear energy- pe stored in atomic nucleus: kinetic energy- energy of motion. Thermal energy- ke from moving atoms and bonds. Radiant energy (radiation)- ke in electromagnetic waves. Energy sources: sun- weather, plants, coal, oil, natural gas. Earth"s internal heat: volcanos, earthquakes, plate tectonics. Laws of thermodynamics (rules about energy: 1. Energy cannot be created or destroyed (just changes form: 2. Disorder increases in a system (energy gets changed ti less useful forms) Ideal gas law: pv= nrt, p= pressure, v= volume, t= temp, compressing gasses gives off energy as heat, decompressing gasses absorbs heat. Density: mass/volume, density affects plate tectonics, density affects pollution, affects atmospheric.
